position, that the pins, S, S', shallfalways" bear against fthe" levers E, E'. SlfThe pulleys, U, U', have -a certain `number of grooves cut on thefperiphery, the?n umbervarying=y .according i to 1 the size'' and -descniiption' fof,"

boxes, `f,which are required` to be made. The teeth cut onthe projectionsl of the pulleys, U, U', as before mentioned are of equal number, with `the number of grooves on those pulleys.

X, X', are levers turning on centers, 7c, lo',

fast to the supports, Q, Q', the upper ends of which fit into the grooves cut on the pulleys, U, U'. 'm,'m', are springs likewise fast to the supports, Q, Q', and so arranged` as to act against the levers, X, X', in such manner, as to kee-p t-he same, at given moments, in the grooves of the pulleys, U, U', and thereby preventing theupper shafts, V, V', from turning. p, p', are pins or projections fast to the standards, P, P', or to 'the bedplate, A, and so arranged that whenthe lower end of the levers, X, X', come in contact with the same, said levers are thrown out of the grooves of the pulleys, U, U', setting thereby the same at liberty and allowing the upper shafts, V, V', to be turned as will be hereafter described.

S are guides for the wood, out of which the boxes are to be turned, and screwed to the o-utside of thebedplate. i i

u, u', are standards screwed to the bedplate having on one side guides fw for the wood screwed on, and on the other side framesw, in which said frames the outer end of the tool holders, K, K', are guided.A

I is the main driving shaft running in gearings, a, fast to the bedplate A.

4, is a bevel wheel keyed on the shaft I runningv in a corresponding bevel wheel, 5, keyed on the shaft, C", and from which the motion is communicated to the shafts C through the connecting rods c and cranks d.

6, is a pinion fast on the shaft I working in a wheel, 7 fast on an intermediate shaft I' resting in bearings attached to the bedplate.

8, is a pinion fast on the intermediate Shaft I' working in a wheel 9, fast on the shaft O, which latter runs in bearings a' attached to the underside of thebedplate A.

J are frames screwed to the bedplate A and carrying the centers A', B', G, and G'.

R' is a cam fast on the shaft O.

i E, E', arelevers turning upon the centers, G, G', the lower end of which rest against the two sides of the cam, R', and the upper end against the pins, s, s', fast on the pulleys W, W'.

S' is a second cam fast on the shaft O.

F, F', are levers turning upon the center A',the lower end of which rest against the two sides of the cam S' and the upper ends against the project-ions, T, T', fast to the frames R.

D' is a third cam fast on the shaft O. H, H', are levers turning onl the center B' the .lower end of said levers resting against the twosi'des of the cam D and the upper q ends against the projections, Y, Y', fast to the frames N, N'.

Fig. 4, represents the cones M, M', separate. The same are so constructed that the distance, a' b', is equal to t-he radius of the ,largest size boxes capable to be made upon `a machine; it follows therefore that the frames N, N', to which those cones are attached must move the distance, a' c', if the largest size boxes are made; but if a box be made whose radius is equal, a" b', then the distance necessary for the frames, N, N', to move, will be only equal to, a" o", and the time required for this operation is then in proportion as the distance a' c' is to a" c".

Fig. 7, represents the cam D' by which the frames, N, N', through the levers, H, H', are moved. This cam is so constructed that the height o" t is equal to the amount of motion required to be given to the frames N N'.

'Fig 6, represents the cam S by which the supports, Q, Q', are moved through the levers, F, F'. This cam is so constructed that the surfaces from l to 4 are concentric with its center, but'of different radius and this space be equal to the time those supports are required to remain stationary, it follows therefore that when the levers, F, F', are in contact with the surfaces of this cam, during the space from 4 to l those supports will be moved either to the right or to the left. The difference between the radius O y and the radius O y' is equal to the distance said supports, Q, Q', have to be moved, and which distance must be equal to the depth the wood requires to be bored out.

F ig. 5, represents thecam R' by which the pulleys, W, W', through the llevers, E, E', are turned upward and as those pulleys are then locked to the pulleys, U, U', which latter pulleys are keyed fast to the upper shafts, V, V', that motion is communicated to said shafts. When the box is finished and cut off, the wood has to be moved toward the toolholder, first the depth, the hole has been bored out, and secondly, the thickness of the bottom of the box.

On the cam R' the height d' fw' is made equal to the depth the hole has been bored out, and by the before described connection the wood is therefore brought as much toward the toolholder, and the space from 3 to 4 is the time allowed for said operation,

while the heights d" 'w" is made equal to position, and connected then by gearing in the usual manner with the shafts C' and .O in such manner as to give to said shafts the required speed.

The operation of this machine is as follows; In the position represented n the -`following drawing (where in Fig. 11,the

wood is representedinre'd lines) the-wood lwoodis 'clear of the tools g" and 7L and ready to be cut olf, in whichlposition the woodV is yheld nowstationary. Now setthe machine in motion, when the toolholders will be set -revolving as welll as the shaft O, through the respective gearing as before described. Whilethe shaft O turnsxthrough'the space from-1 to2 theleverH is acted on by the projection, 0;15, on the cam 1D and presses the frame N', with theccones M attached,

forward, thereby compressing `the springs r. By this forward mot-ion of sa'id'frame the :arms a are-forced up, the. inclined vsurvface of the cones M, turning the spindles band consequently'thefknives f lso as t0 bring-the lattertoward the center of the wood, by which operation ltheboX is cut off.

Secondly. .While t-he shaft'O turns through the space from2 to 'the'lever H falls from thefprojection, 0 t, of 'the camD to its original surface, and the spring r, compressed by the before described action, forces the frame N back-again to its first posit-ion by -which backward motion the arms n on theA spindles Z are relieved and forced back again by the action of the spring o thereby vbringing the knives f to the outside periphery of the wood and out of action. In the position `represented in ,the .drawing the lower ,end of the lever Xhas come in contact wit-h the pin or projection p and has, by said pin, beenthrown out of one of the grooves on the pulleys U setting thereby the latter at liberty to'zbe turned. The spring o of the pulleys l/Vfits likewise into one of the teeth on the projections on the pulleys U, and locking thereby the two pulleys together.

Thirdly. While the shaft O turns through the space from 3 to 4 the projection, d fw', on the cam R has acted on the lever, E, pressing thereby the pin s, fast to the pulley W, upward, and as this pulley is now locked to the pulley U, as b efore described, the upper shaft ,V is partly turned around thereby advancing the wood toward and into the toolholder K', as much as the dept-h of the hole, the wood has been bored out. l/Vhile the shaft O has turned through the space from 1 to 4 as just described, the

levers F and F have rested on that part of 'the:frames R, :(which saidframes connect kthe supports, .as has been before described,) Vthe supports QYQ from the right 4handito the'left, forcingthereby on the right hand `the wood into the toolholder K and against lthe boring tool g and afterward against the tool L, whereby the wood is bored out and the groove for the cover turned on; and at the lefthand yof the machine, the wood is brought out of the toolholder K, clear of the boring tool g, as thismotion is' equal to the depth,the hole hasvbeen bored in, .as before described. During this time, that the shaft O'turns through the space from 4 to-l t-he cam R acts still von the lever E giving tothe same kand therefore to the pulleys .U and WV (as those two pulleys are still lockedtogether) and consequently to the wood between the ratched wheels e a second motion, in combination with the one just described, andfwhich said motion is equal to the thickness of the'bottom of the box. The wood, on the right hand side, receives therefore, during this time, itwo motions, one frdm the movement of the supports Q, Q, and o-ne from the motion communicated to the upper shaft V through the pulleys U5- and lV, and which said two motions are together equal to thev whole length of the iboX. pressed into the toolholder K, as just described, the knives, i, turn the outside of the.` same.

By'the motion of the supports Q and'Q the lower end of the lever X has come clear of -the pin 79 and is now throughthe action of the spring m pressed against the periphery of the pulley, U, and falls at the moment the abo-ve described motion of the supports, Q, Q, is finished, into the neXt groove of the pulley U, holding thereby the same, and consequently the upper shaft V, stationary, until the lever X comes again in contact with the pin or projection p, in the backward mot-ion of the supports.

While the shaft O has turned through the spaces from 3 to l the lever E has moved down the incline on the cam R. The pulley WV is then acted on by theweight Z attached to the cord passing around the periphery of ksaid pulley, thereby pulling the pulley W around, in such manner as to keep the pin s always against the lever E. During this time the internal spring o slides over the back of a tooth cut on the projection of the pulley U until it falls into the next tooth. The upper end ofthe rod X is held by the spring m in one of the grooves of the pulley U, preventing thereby the same from turning while t-he pulley W is turning backward on the projection of the, pulley U as just described. l

During the time, that the shaft O has made one half revolution, as has just been described, the wood on the left handside of While `the ywood is the machine has been brought clear of the borer g and the boxes on this side are now ready to be cut off, While from the Wood on the right hand side one set of boxes haveV been cut olf, the Wood been again sufficiently advanced, and has been bored out and the recess for the cover turned on.

By the second half revolution of the shaft O the above mentioned operation Will be repeated, only with this di'erence, that those operations, which have been described as having been performed on the right hand side of the machine, Will novv be performed on the left hand and vice versa. By every one Whole revolution of the shaft, O, two sets of boxes Will therefore be turned, bored, and cut off, that is of the largest size boxes capable to be made in a certain machine.

To make different sized boxes the cams, R', S', D', must be changed for others similar as regards construction, but differently divided as regards to space each projection occupies, and the pulleys U and U' must be changed for similar ones, but having a greater number of grooves and teeth. F or example, if it is desired to change these cams and pulleys so as to be able to make a size of boxes half as large in every respect, then on the cam D' the height 0" t requires to be only one half of the former and it requires, consequently, only one half of the time,` for the operation to be performed in, and the same will be the case With the cams, R', S', and the pulleys U and U' Will receive twice the number of grooves, as Well as twice the number of teeth on their proj ec-v tions, consequently We shall be able to make of this kind of boxes 4L sets by every one Whole revolution of the shaft O and so on in proportion to the size of boxes.

What I claim as my invention and'desire to secure by Letters Patent is:

1. I claim the means of making different sized boxes on the same machine, by the mere change of the cams, R', S', D', and the pulleys U, U' corresponding to the size of boxes as described.

2. I claim, cutting oil3 the boxes, When finished by tools f or f' fastened to spindles, Z or Z', said spindles being attached to the toolholders, and Worked by an arm lnl or n' fast on the end of the spindles as described.

3. I claim the construction and'application of the frames N or N' with cams, M, M',

respectively, attached, actuating through the arms n or 'n' the spindlesfl or Z' and consequently the tool f or f', said frames being Worked by cams D' and levers H or I-I' as described. y

4. I claim the arrangement and connection of the supports, Q, Q', provided With shafts and ratchet Wheels, between Which latter, the Wood, out of which the boxes are to be made, is held,`said supports being Worked by cams S' and levers F or F', for feeding the Wood to the tools and releasing the same as specified.

5. I claim the construction of the pulleys U and W or U' and W Worked by cams R' and levers E and E' as Well as by Weights Z or Z' as described, said pulleys When connected, acting upon the vupper shafts V or V', running in the supports Q or Q', for approaching the Wood up to the toolholders, after the completion of each set of boxes.
